I am one click away from the sub order Irregardless of the price differential, could y'all comment on the sonic differences between running (2)VTF-3's versus the Dual CS-Ultra Package. The Home theater is located in a "great room" which is open to the rest of the house and therefore has massive cubic volume. I am interested in a subwoofer package that can deliver the goods! I am leaning toward the SVS subs...but I keep hearing great reviews on the HSU subs! The rest of the equipment is: *Denon 5803 *Cambridge Soundworks Newton T500 towers(containing internal 300W subs) *MC500 center *(4)S300 tripoles for the rear "stuff" I know some of you hate anything CSW produces and I tried very hard to not like them myself...but can you believe I picked them over both the Polk Audio LSi25's and the DefTech Bp2000's....I know weird!!!! Now if I can only hide the CSW logo I'll be set!
